Correct Answer: Uninterested

Solution : The third option is the correct answer.

While being "inquisitive" implies a strong desire to explore, learn, or inquire about something, being "uninterested" suggests a lack of curiosity or eagerness to engage with new information.

The meanings of other options are as follows:

• Careful means exercising caution and attention and showing prudence.
• Dull means lacking interest or excitement, not sharp or vivid.
• Indolent means inclined to avoid work or activity; lazy.

Therefore, the correct answer is uninterested.
